To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought this thermos about a month ago. At first it kept my coffee nice and warm. When I put my cold coffee in, a week ago I noticed it didn't keep cold very long but didn't think much of it until today. I put hot coffee I'm my thermos and within an hour or two my coffee was cold. Honestly I'm really disappointed I'm this product.
Just threw it away after just a month of use. Really wanted to love it. Held the purfect amount of steamed milk to send with my son for daycare. There is a spot for dish water to seep into the head where the 'tail' is no matter how hard I tried to keep from submerging it, it got funky and didn't want to deal with bleach every time to inhibit mold growth.
